Definitions

  • the present invention relates to oil-based binders and optionally pitch-based binders, solid when cold and in divided form, and their use as a rejuvenating agent for the production of coatings from recycled asphalt aggregates. It also relates to a method for transporting and/or storing and/or handling binders that are solid when cold and in divided form.
  • the invention aims to facilitate and improve the use of recycled bituminous mix aggregates during the manufacture of new bituminous mixes.
  • Recycled bituminous mix aggregates are materials resulting from the operation of repairing a bituminous surfacing layer, such as road, sidewalk, or sports field surfacing, which are essentially composed of a bituminous binder and aggregates. More specifically, recycled bituminous mix aggregates are derived from the operation of repairing bituminous surfacing which may be either the wearing course or one of the structural layers.
  • Recycled bituminous mix aggregates are essentially composed of aggregates and bituminous binder residues adhering to these aggregates. Bituminous binder residues are also called aged bituminous binders.
  • the rejuvenator must allow both the consistency and the chemical composition of the bituminous binder present in the recycled asphalt aggregates to be adjusted. It facilitates the remobilization of aged bituminous binders present in the bituminous aggregates, that is to say that it mixes easily with the aged bituminous binder and the aggregates both forming the recycled asphalt aggregates. This mixture produces asphalts in which the bituminous binder once again has a consistency and chemical composition allowing it to have the expected mechanical properties.
  • the rejuvenator must make it possible to formulate a composition in which the binder has a satisfactory softening temperature and penetrability.
  • Recycled asphalt aggregates and oil-based binder compositions, possibly with added pitch, are usually used as rejuvenators.
  • binders are currently transported in insulated tanker trucks or in iso-containers that allow heating using a heat transfer fluid or a steam network.
  • the user must be equipped with storage tanks that are also kept hot until the binder is used.
  • organogellants allow liquids to be gelled thermoreversibly.
  • organogellant is capable of solidifying which liquid.
  • the presence of an organogellant in a liquid has an influence on the properties of this liquid and the invention aims to formulate a binder based on oil and possibly pitch, solid at room temperature, without its usage properties, in particular its properties as a rejuvenating agent in the production of coatings from recycled asphalt aggregates, being modified by the presence of additives allowing its solidification.
  • WO 2008/107551 teaches bitumen compositions comprising an organogelator-type additive and having thermoreversible viscosity and hardness characteristics. It is known, in particular, WO 2016/016320 to use organogelling agents to condition bitumens in cold solid and divided form. However, the composition of a bitumen is very different from that of an oil-based binder and possibly pitch, and the intended applications are very different.
  • JP 02 169669 discloses the preparation of bituminous compositions whose olfactory intensity and the quantity of smoke released during their heating are reduced.
  • Bituminous compositions include bitumen, a styrene-based thermoplastic elastomer and dibenzylidene sorbitol.

  • one aim of the invention is to provide an oil-based binder and optionally a pitch-based binder, which is in divided and solid form at room temperature, and which can be mixed with recycled bituminous mix aggregates in order to produce bituminous coatings.
  • an oil-based binder and optionally a pitch-based binder in solid form and in divided form, comprising an organogelling agent whose presence does not significantly modify the usage properties of the rejuvenating composition or the rejuvenating binder, nor those of the bituminous mix compositions in which it is incorporated.
  • the invention also aims to propose a method for transporting and/or storing and/or handling at room temperature a binder in solid form and in divided form.
  • Another objective of the invention is to propose a method allowing easy handling of the binder during handling operations.
  • Another objective of the invention is to propose an ecological and economical method for transporting a binder and to avoid the use of additional means for maintaining the temperature of this binder during its transport and/or its storage and/or its handling.
